EDGAR PECKIIAM, OF KINGSTON, NEI/V YORK, ASSIGNOR, BY MESNE ASSIGN-`MENTS, TO THE PECKHAM lMOTOR TRUCK AND WHEEL COMPANY, OF

SAME PLACE.

CAR-TRUCK.

SPECIFICATION forming part of Letters Patent No.' 464,253, datedDecember 1, 1891.

Application lled October 30, 189Q. Serial No. 369,787. (No model.)

To all whom it may concern.-

Beit known that I, EDGAR PECKHAM, lof Kingston, inthe county of Ulster,in the State of NewYork, have invented new and useful Improvements inCar-Trucks,of which the following, taken in connection with theaccompanying drawings, is a full, clear, and exact description.

This invention relates to the trucks of electric cars carrying the motoron the trucks.

The chief object otl the invention is to provide the truck with a motorsupport or hanger which shall permit the armature to be readily removedthrough either the top vor bottom of the truck, and also allow the motorsufficient lateral play to avoid cramping the same when the car istraversing a curve in the road.

The object of this invention, also, is to utilv ize the coupling-boltsof the car-springs for staying the car-body laterally, so as to preventits shifting from its requisite position over the truck.

To that end the invention consists in the improved construction andcombination of parts hereinafter fully described, and spe cically setforth in the claims.

In the annexed drawings, Figure lis a side elevation of a car-truckembodying my improvements. Fig. 2 is a vertical transverse section online a: oc, Fig. 1 Fig. 3 shows enlarged vertical transverse section ot'the niotor-hanger. Fig. 4 is an enlarged vertical transverse section ofone of the car-springs with the lateral stay of the car-body, and Fig. 5is a top plan view of the truck.

Similar letters of reference indicate corresponding parts. y

A A represent the car-wheels fixed to their axles A A', which arejournaled in the boxes C C in the usual and well-known manner.

` Upon the boxes C C are hung the yokes a o.,

`nally over the truck.

tached longitudinal bars B B which extend nearly or rquite to the endsof the car and have the life-guard R attached to them and extendingbeyond the end of the car-body. The said bars B and B are braced by alongitudinal truss-bar D, secured to the lower ends of the inner limbsof the yokes ct a, and end braces D D extending upward from the lowerendsv of the outer limbs of the yokes and attachedl to the bars B B somedistance from the yokes. Straps D D extend across the lower ends of theyokes and are connected thereto and to the adjacent portions of thetruss bars and braces D D by means of bolts which are removable to allowthe journal-boxes to be removed downward from the truck-frame whendesired. The car-body is supported on ,the side bars B B andBB byspringsb b. To stay the body both laterally and longitudinally over" the truckand at the same time retain the springs b b vertically on the truck, Irigidly attach either to the car-sill or to the longitudinal top bars II depending posts c c, which-pass through caps d, springs b, andbase-plates f of said springs, and are allowed to slide vertically inthe same, as shown in Fig. 4 of the drawings. The said base-plates beingfirmly attached to the bars B B serve to guide the posts c c verticallyand prevent the car-body from shifting either laterally or longitudi-The caps ol of the springs being usually thin plates,I form withdownwardly-extending tubular bosses d',

which receive the posts c c through them, as shown in Fig. 4 ot thedrawings. Said tubular bosses serve as guides for said -posts and forthe caps. The free ends ofthe bars B B I provide with additionalsupports by connecting said portion of the bars to the carbody by meansof spring-hangers U.

In order to obviate obstructions to mounting on the Ytruck a car-bodyhaving crossbeams secured to the under side of its end portions, and toalso afford ample room to accommodate a rheostat when desired to beapplied to the truck, I-dispense with the crossbars, which are usuallyattached to the ends of the side bars of the truck-frame,`and in lieu ofsaid end cross-bars I tie the two sides of the truck-frame together bymeans of crossbars m m, secured to the lngitudinal top beams I I of thetruck near the wheels A A, as best seen in Fig. 5 of the drawings.

Between the journal-boxes on each side of the truck I mount on the barsB B one or two pedestals P P, according to the number of motors to beconnected to the truck. Said pedestals, rising from the side bars B B,are inserted between the bars B B and preferably supported thereon byshoulders g on the pedestals riding on top of one of the bars B. Bymeans of bolts h, passing transversely through the said bars andintervening portions of the pedestals, the latter are retained inposition. Each of the pedestalsP isformed with a downward extension Pthe lower end of which is bifurcated and embraces thereby the lowerlongitudinal truss-bar D, as shown more particularly in Fig. 3 of thedrawings.

The upper end of the pedestal is formed with a horizontal offset Pextending inward some distance beyond the inner bar B, and this offsethas an eyet extending vertically through it. Through thiseye passes theshank of a bolt j', which is secured in a suspended position by nuts n nand washers o 0, connected to the bolt above and below the offset P.

To the lower ends of the two bolts jj, at opposite sides of the truck,are pivotally connected two parallel cross-bars F F, and to saidcross-bars, at a point about midway between the bolts jj, is secured themotor-support Il. In order to allow this support to rock laterally, Imake the eye t' sufficiently larger than the bolt to allow the latter tomove laterally and interpose between the offset P and washers 0 osoft-rubber cushions t t, and by surrounding the portion of the boltwhich is in the eye t' with a rubber tube or lining t the motorhangerbecomes insulated from the truckframe. The motor-support II may be ofany suitable construction, according to the style of motor employed. Mypreferred form of the motor-support consists of the prop L, which ismounted on the cross-bars F F and is rigid and formed with adownwardly-projecting tenon u, which passes between the cross-bars andis bolted or riveted thereto. Over the top of the aforesaid prop is theheel N ot' the motor. Between this heel and top of theV prop isinterposed a soft-rubber cushion t), and a similar cushion is placedupon the heel N. Vertically through the two cushions and interveningheel and through the prop L is a bolt-hole for the reception of the boltfu',

which is provided with nuts and washers w at both ends. may be insertedbetween the bottom of the cross-bars F and subjacent washer w. By meansof the aforesaid nuts the heel of the motor is securely retained on itssupport. The aforesaid cushions serve to relieve the motor from thesevere jars incident to the vertical thrust of the heel of the motorwhen starting said motor. By placing on the portion of the If desired,another cushion n bolt t" which is within the heel N a bushing of rubberor other non-conducting material the motor becomes insulated from itssupport II.

I-Iaving described my invention, what I claim as new, and desire tosecure by Letters Patent, is v l. In an electric-motor truck, thecombination, with longitudinal side bars supported on the journal-boxes,of pedestals mounted on said side bars and rising from the same,crossbars suspended from said pedestals, and a motor-support mounted onsaid crossbars, asset forth.

In anI electric-motor truck, the combination, with longitudinal sidebars supported on the journal-boxes, of pedestals mounted on said sidebars and formed with inward offsets, bolts suspended from said offsets,crossbars connected to said bolts, and a motor-sup# port mounted on saidcross-bars, as set forth and shown.

3. In combination with the longitudinal side bars supported on thejournal-boxes, pedestals mounted on said side bars and formed withinward offsets, bolts suspended from said offsets and oscillatorylaterally in their connection, cross-bars pivotally connected to saidbolts, and a motor-support on said cross-bars, as set forth.

4. In combination with the side bars B B and truss-bar D, the pedestalP, secured to said side bar and formed with the downward extension P',connected to the truss-bar, substantially as set forth and shown.
